Abstract
A low profile fairlead has a plurality of blocks support in a spaced relation along the arc of a circle to simulate a single bearing block of larger diameter.
Claims
exact text as granted — not AI-modifiedI claim:
1. A fairlead multiple bearing block assembly for supporting a flexible line, said assembly comprising at least three adjacent sheaves, each sheave comprising an inner race and an outer line receiving race rotatable about the inner race, said sheaves being arranged in a common plane to receive the line and having parallel axes of rotation intersecting a common arc having a diameter larger than the diameter of the sheaves, side plate means for connecting the inner races of said sheaves in a fixed relation to form said assembly, and an upright fitting outside of said arc for securing said sheave assembly to a base support, said fitting comprising an arm, first pivot means between said side plate means and said arm to enable pivoting of the sheave assembly about a first axis parallel to the axes of rotation of the sheaves, second pivot means between said arm and the side plate means to enable pivoting of the sheave assembly around a second axis perpendicular to and intersecting said first axis, and third pivot means between said base and said arm in the plane of the sheave assembly to enable said assembly to swing laterally.
2. The assembly of claim 1 wherein said sheave assembly comprises a centrally located sheave, and wherein said second axis is perpendicular to the axis of rotation of said sheave.
3. The assembly of claim 1 additionally comprising a track secured to said support, and a car slidably mounted on said track, said car and said arm being connected by said third pivot means.Cited by (0)
